4 Ton 14.5 SEER Goodman Air Conditioner with Vertical 24.5" Cased Coil Review 2026

// Bottom Line

This 5-ton vertical A-coil is ideal for contractors upgrading existing GSX16S481 units or homeowners in moderate climates seeking dependable cooling without premium costs. The SEER 16 rating and Energy Star certification make it a smart choice for those balancing efficiency gains against budget constraints.

Review

This Goodman vertical cased coil represents solid middle-market performance in the 4-5 ton cooling segment. The 45,500 BTU cooling capacity and SEER 16 efficiency rating position it above basic equipment while maintaining accessibility for contractors managing tight project budgets. Online Supply's $117 price point is competitive for Energy Star certified coils, making this a practical upgrade path for existing Goodman systems or new installations where premium variable-stage technology isn't justified.

Real-world performance hinges on the single-stage scroll compressor design operating on 208/230V single-phase power. At 73 dB, noise output is moderate but noticeable in quiet neighborhoods. The 3/8" liquid line and 7/8" suction line with 3/4" insulation match standard residential installations. Refrigerant compatibility with both R410A and R22 provides flexibility for mixed-system retrofits, though R410A is recommended for new builds. The coil weighs 30 pounds, making solo installation manageable for experienced technicians.

Pros & Cons

Pros

SEER 16 efficiency rating delivers measurable energy savings compared to standard 13 SEER units, typically 15-20% lower cooling costs annually
Energy Star certified, qualifying for potential utility rebates and tax incentives in many jurisdictions
Single-stage scroll compressor is proven technology known for reliability with minimal moving parts
Vertical 24.5" cased coil configuration fits tight spaces where horizontal units won't work
10-year warranty with online registration provides solid long-term protection at this price point
Direct replacement for GSX16S481 simplifies retrofit installations with minimal ductwork modifications

Cons

Single-stage compressor lacks variable capacity, cycling on and off rather than modulating, reducing part-load efficiency and comfort
73 dB noise level is noticeably louder than two-stage or inverter-driven alternatives, which can range from 65-68 dB
Specs show conflicting tonnage ratings (4 ton in title, 5 ton in specs), creating confusion about actual cooling capacity

Who Should Buy

Best For

Contractors performing equipment swaps on existing installations will appreciate the direct GSX16S481 compatibility and quick commissioning. Budget-conscious homeowners in mild-to-moderate climates benefit from the SEER 16 efficiency without paying for variable-stage technology they may not need.

Consider Alternatives If

Those in extremely hot climates like Phoenix or Miami, or noise-sensitive installations near bedrooms, should explore two-stage or variable capacity models that cycle less frequently.

Installation

Installation requires standard HVAC practices: copper line sizing per manufacturer specs, proper evacuation to 500 microns, and nitrogen pressure testing before refrigerant charge. The vertical A-coil orientation fits 24.5" width spaces common in basements and mechanical closets. Upflow/downflow configuration flexibility accommodates both heating and cooling airflow directions. Most residential installations complete in 2-3 hours with two technicians.

Warranty & Reliability

The 10-year parts warranty with online registration is straightforward and competitive for this price tier. Registration is mandatory to activate full coverage, so contractors must document serial numbers and installation dates. Coverage includes compressor failure, refrigerant leaks, and component defects. Excludes labor and damage from improper installation, lack of maintenance, or improper charging.

Frequently Asked Questions

What does SEER 16 actually mean for my monthly cooling bill? +

SEER 16 means this unit removes 16 BTU of heat per watt of electricity consumed. Compared to a 13 SEER unit, expect 15-20% lower electricity use for cooling, translating to roughly $25-50 monthly savings in moderate climates. Results vary by local electricity rates, humidity, and thermostat settings.

Can I install this to replace my old Goodman GSX16S481? +

Yes, this is a direct replacement. Existing copper lines, electrical connections, and ductwork typically require no modifications. You'll need to verify refrigerant type compatibility and check superheat/subcooling during commissioning, but most retrofits install without major structural work.

Will this unit work with my 230-volt residential service? +

Yes, the unit operates on 208/230V single-phase 60 Hz power with 23.9-40 amp breaker range. Your existing 230V service is compatible. If your home runs 208V, verify compatibility before purchase, as some older systems use 208V exclusively.

How does single-stage compare to two-stage cooling for my needs? +

Single-stage cycles fully on/off, consuming more energy during part-load conditions. Two-stage runs at lower capacity most of the time, improving efficiency 5-10%. Choose single-stage for mild climates and price sensitivity; choose two-stage for hot climates or maximum efficiency.

Is the 10-year warranty good enough protection? +

Yes, it's solid for this price. Most compressor failures occur within 5 years. At 10 years, you're protected against manufacturing defects but should budget for eventual replacement around year 12-15 anyway.
